As a steel detailer, one of the most common questions I hear from engineers, contractors, and clients is: “Should we go with PEB or Conventional Steel?”
Both systems have their place, but from a detailing point of view, they differ in terms of design, drawings, fabrication, and even the challenges we face during execution.
How PEB Works for a Steel Detailer
In a Pre-Engineered Building (PEB), most of the design is standardized and optimized in the factory. As a detailer, this means:
- The connection details are usually pre-defined.
- Drawings are modular and repetitive, which reduces drafting time.
- Less coordination is needed because fabrication accuracy is high.
- Fewer revisions since the design is already optimized for steel weight and economy.
In short, detailing for PEB is more about preparing clear assembly drawings and erection plans rather than developing custom connections for every joint.
How Conventional Steel Affects Detailing
In Conventional Steel Structures, the approach is different:
- Every project is unique, so we prepare detailed shop drawings and custom connection designs.
- More time goes into coordinating with structural engineers to confirm loads and connection types.
- On-site fabrication requires precise detailing to avoid errors.
- There’s a higher chance of revisions as architects and engineers may adjust designs during the project.
For detailers, conventional steel is more challenging but also offers more scope for creativity and problem-solving.
PEB vs Conventional Steel in Steel Detailing
| Aspect | Pre-Engineered Building (PEB) | Conventional Steel Structure |
|---|---|---|
| Drawings | Standardized, repetitive, faster to prepare | Custom, project-specific, time-consuming |
| Connections | Factory-defined, fewer variations | Designed case by case, many variations |
| Coordination | Less back-and-forth with engineers | Continuous discussions and revisions |
| Fabrication | Factory-controlled, high accuracy | Site-dependent, more tolerance issues |
| Erection | Easy bolt connections, faster assembly | Mix of bolted and welded joints, slower erection |
Advantages of PEB for Detailers
- Quicker turnaround for drawings.
- Fewer RFIs (requests for information) since design is standardized.
- Less rework because fabrication is factory-controlled.
- Easier for site teams to follow erection drawings.
Why Conventional Steel Still Matters
Even though PEB saves time, conventional steel detailing is essential for:
- High-rise buildings.
- Bridges and heavy industrial plants.
- Unique designs where no standard module applies.
These projects need a detailer’s expertise to ensure every connection is practical, safe, and easy to fabricate.
Final Word as a Detailer
From my experience, PEB is best when speed and cost are top priorities, while conventional steel is best when complexity and customization are required.
For a steel detailer, PEB means efficiency and speed, while conventional steel means more technical involvement and problem-solving. The choice depends on the project’s goals, but either way, accurate detailing is what turns the design into a safe, buildable structure.
